Crypto Trading and Gambling are both involves a risk but for me it would be much better to go trading although you need to have a skill and a knowledge also it takes time before you can get a profit but still it is a good choice for people who's looking for possible profit . gambling could be good but getting greedy will only cause you a big loss and frustration .
Gambling is a short period game, and Trading will take some time, but profit is confirmed if you do trade with the right person. I will also prefer trading it needs more knowledge and skills. Sometimes we will get loss in trading it will help us how to trade in next time. But in gambling, we can not learn any new thing here if you lose your bet next time if you use the same strategy you may win. So the gambling is unpredictable game.
I agree with your last statement gambling really unpredictable and thats the advantage of trading we do have lots of resources to review every entry that we are going to invest as news all over here or other sorts of information can be found with the help of internet but in gambling without your luck even you are already a pro you are still risking your money.
